The Hadrosaur location was in a dry wash which flows into Frank Creek, then into Glendive Creek and then into the Yellowstone River just North of Glendive Montana in the NW ¼, NE ¼ of Sec.
32, T16N, R56 E, Dawson County, Montana about 13 km south-east of the Triceratops location according to Otis Kline (2). 1 and Fig 2 were taken during excavation for the Triceratops femur.
Abstract: The discovery of collagen in a Tyrannosaurus-rex dinosaur femur bone was recently reported in the journal Science.
Its geologic location was the Hell Creek Formation in the State of Montana, United States of America.
It is very slippery in wet, and crunchy in dry condition, according to paleontologist Otis Kline.
Rivers draining the Western Mountains deposited layer upon layer of sediments which over alleged millions of years compacted to form the sandstones, mudstones, clays, and shales that form the Montana Badlands landscape according to the Makoshika State Park web site. It usually refers to any clay that swells and shrinks.In light of the discovery of soft tissue in a T-Rex from the Montana Hell Creek Formation and RC dates for other fossils in the geological record it was decided to examine the bone interior of this femur, as Libby's team did with Smilodon and Schweitzer et al. 2a to 2d shows the support system including Plaster of Paris and wooden support base.did with the T-Rex "hind limbs." The Triceratops femur bone was discovered in what is called "popcorn clay." Since the bone was so huge (122 cm long and 20 cm through the shaft area) and completely intact [hard, and neither crushed nor deformed, ideal for extracting possible bone collagen] it was sawed open in late July 2005 near the proximal end, as shown in Fig. The Triceratops femur was resting on a layer of popcorn clay in an apparent, almost aseptic sand and fine clay matrix.Fig.3a shows the Triceratops femur dissection using carefully cleaned saw with the bone supported by wood frame and plaster of Paris cast.
Identification of the femur was made by comparing with photos and descriptions from a standard paleontology text-book and comparison with a young adult femur, 107 cm long.When it was learned in 2005 that Triceratops and Hadrosaur femur bones in excellent condition were discovered by the Glendive (MT) Dinosaur & Fossil Museum, Hugh Miller asked and received permission to saw them in half and collect samples for C-14 testing of any bone collagen that might be extracted.
